Re: Delta G°
When ΔG=0 then the system is at equilibrium, not when ΔG° is 0. G° is standard free energy of a gas at 1atm. If G°=0 I believe it means there is no free energy due to change in pressures.

Re: Delta G°
Looking at the equation deltaG°=-RTlnK, if K=1, that means the products and reactants are of the same concentration, and thus lnK=0, and deltaG° will equal 0.

Re: Delta G°
In an equilibrium reaction, delta G is equal to zero when the reaction reaches equilibrium. This is because at equilibrium the free energy of the reactants equals the free energy of the products, making the difference in free energy zero.
